LAMP-CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 274,489, dated March2'7, 1883.

Application filed February 5, 1383. (No model.)

tant advantages are gained, all as will be here inafter fnllydescribed,and particularly pointed out in the claims.

In the drawings hereto annexed,Fi gnre l is a perspective view of oneform ofniy improved lamp-chimney attached to the burner. Fig. 2 is ahorizontal sectional view of the same. Fig; 3 is a perspective viewshowing a modification. Fig. 4 is a horizontal sectional view of thesame. Fig.5 is a perspective view showmg another modification, and Fig.6 is a horizontal sectional view of thelatter.

The same letters refer to correspon din g parts in all the figures.

My invention' consists, essentially, ot'alampchimney bisected verticallyand consisting of two equal or nearly equal parts.

In Fig. l the said parts, which are denoted by letters A A,arerepresented as being made oi glass and connected at the top and bottomby bands B B,which may be of metal, or of any other suitable material.Between the glass sections A A is interposed a partition, 0, of metal,the sides of which are preferably brightly polished, so as to act asreflectors. This form of chimney is intended and adapted for burners ofthe kind represented in the drawings by letter D, which, it will beseen, is

a double burner provided with two wicks fed by the same reservoir, outoperated independentlyby separate wick-raisin g mechanism. It will beseen that one or both of these burners may be lighted at the same time.When both are lighted, the lamp will throw the light in two directionsby reason of the central reflector, G; or either burner may be usedsuccessfully independently of the other.

In Figs. 3 and 4 of the drawings I have shown a modification whichconsists in omitting thecentral partition, 0, and making one of thehalves or sections of the chimney,which is denoted by letter E,ofn1etal,the inner side of which is brightly polished, so as to act as areflector. The other section, A, is made of glass, as above. The partsare held together by the bands B B at the top and bottom, and Iprefer toprovide the edges of the metal section E with grooves F F, to receivethe edges of the glass section A and hold the latter securely. In eithercase the lower edges of the parts or sections may be suitably creased orotherwise constructed for attachment to the burner.

In Figs. 5 and 6 of the drawings both parts or sections A A areconstructed of glass, without any metallic partition interposed. The

parts are held together by the bands B B, and

form, when thus constructed, a plain verticallybisected chimney.

In all the forms of my improved lamp-chimneys the connecting-band at thebottom may be dispensed with, and the screw, springs, or otherlamp-fastening relied upon to hold the parts together; I may also findit desirable, when the central partition is used, to provide the saidpartition with flanges on both sides, as shown at G, to receive theedges of the glass sections, which are thus held securely, while at thesame time a tightjoint is formed.

The operation and advantages of my invention will be readily understoodfrom the foregoing description, taken in connection with the drawingshereto annexed. The bisected chimney is not liable to break or crack, ascontraction and expansion are allowed for. They may be manufacturedcheaply, and may be shipped at much less expense than ordinary.chimneys, as they may be packed closely together. The metallic partitionand the metallic section both form excellent reflectors, and when thechimney having the partition is used with my double burner a brilliantlight is secured.

I claim as my inveniionand desire to secure by Letters Patent of theUnited States- 1. A vertically-bisected lamp-chimney haw ingametallicpartition interposed between the two parts or sections of which it iscomposed, substantially as set forth.

2. The combination ,with a vertically-bisected lamp-chimney, of ametallic partition-plate '2 QWEALSS) between the parts or sect-ions ofthe same,and metallic bands connecting the parts at the top adapted tobe interposed between the parts or sections forming the chimney, andhaving flanges on both sides to receive the edges of and bottom,substantially as set forth.

said parts or sections,substantially as set forth. In testimony that Iclaim the foregoing as r5 5 3. Thecombination,withavertically-biseotedmy own I have hereto affixed my signature in lamp-chimney having ametallic partition inpresence of two Witnesses.
